If the universe were compacted to a singularity would elemental particles survive?

Depends on the mechanism, but generally big crunch means nothing survives except maybe energy.
here is one specific scenario:

In physical cosmology, the Big Crunch is one possible scenario for the ultimate fate of the universe, in which the metric expansion of space eventually reverses and the universe recollapses, ultimately ending as a black hole singularity.
